  Conversion of Crumb Rubber Tires (CRT) and waste plastics to functional materials has been shown in this research study as a feasible approach for the improvement of some physical properties of asphalt. The rheological study of the modified asphalt is made through softening point temperature, penetration point, and viscosity tests. In the present study, CRT and Low Density Polyethylene (LDPE) (plastic wastes) were chosen to be the materials of choice to blend with the virgin asphalt. The reclaimed rubber in the form of powder having a particle size below 0.8 mm was used as an additive to liquid asphalt using the Hot Mix Asphalt Process (HMA) at 180.0 ± 2.0°C with a high-speed stirrer rotating at a speed of 3000 rpm for 60 min. For a consistent mix, the blending operations were performed with different CR and LDPE contents; they were 3.0%, 5.0%, 10.0% and 15.0% by wei.. Read More»
